Summer’s slow demise in late August/early September urged me to acknowledge the need for letting go. Tiny warblers seem to suddenly disappear as they head south. Canada geese begin their practice runs, forming loose “V’s” while trumpeting across the sky. Hummingbirds feed ravenously at any available nectar, gaining 25-40% of their body weight before the long journey to Mexico. Some fledglings still flutter, cry and pursue their parents for a meal; others hone their newly acquired foraging skills. Spiraling through the trees, they seek out the feast of eggs or caterpillars that the pollinators left behind. The meadows quiet down as molting birds hide their bare heads in the greenery hoping to be unseen. Wasps buzz above our outdoor meals, struggling to supplement diminished sources of food.
I spent quiet hours at the newer, eastern section of Stony Creek Ravine Nature Park during these waning days of summer. Come join me in the thinning sunlight and share the ebullience of young birds, the sprays of grasshoppers beneath my feet, and the persistence of butterflies on late summer blossoms that are hallmarks of this transitional season of the year.
Birds, Experienced and Not-so-experienced, Forage and Flutter
I spent my days at Stony Creek Ravine exploring the open fields visible from the top of the Outlook Hill in the eastern section of the park. Much of this area is fenced in to protect small shrubs and trees planted in the re-emerging wetlands. Thousands of native plants were sown there when the old drainage tiles from previous owners were broken to allow water to flow again to the surface. In the spring, pools form and migrating waterbirds glide in for a bit of R&R.
Right now, though, the fenced-in sections are moist but little standing water remains after a hot summer. Social birds flock to the fences to chatter together. Solitary birds, some unusual ones this season, forage within the fence boundaries. Other just need a place to periodically perch while scouting for seeds among the tall grass and flowers within or around the fencing. My photographer friend, Bob Bonin, generously shared some of his excellent photos of birds he came across while patiently waiting near the fence line. It was the right place to be, as you’ll see below!
Young Fledglings Practice Their Foraging, Flying and Landing Skills
One of my mornings at Stony Creek Ravine was in the company of Stewardship Manager Dr. Ben VanderWeide’s Wednesday bird walks. As we entered the park, we spotted several young Eastern Bluebirds (Sialia sialis) whisking in and out of the shrubbery, bits of blue on their wings shining in the sunlight. Three of them spent a remarkable amount of time exploring a hole in a distant snag. We wondered if, being cavity nesters, they were just curious about holes in general or if this hole might have been the one from which they fledged only weeks before.
On another visit, an adult Eastern Kingbird (Tyrannus tyrannus) regally surveyed the area from the tallest branch of a bare tree. Perhaps the adult I saw (below left) was keeping its eye out for its offspring, a juvenile that Bob Bonin saw a few days earlier (below right.) Both birds will shortly be heading to forests in South America where they will feast on fruit during the winter. [Click on photos to enlarge.]
Bob also spotted a female Orchard Oriole (Icterus spurius) and perhaps one of her offspring. Like their bright orange relatives, the Baltimore Oriole, these birds build pouch-like nests. They breed in our parks each year but are less noticeable to most of us. The male is a dark russet orange and black and the female is yellow. Orchard Orioles depart for their overwintering grounds earlier than many other birds, so by now they’re on their way to Central America.
I fell instantly in love with this little puffball. Local bird expert, Allen Chartier, tells me it’s a juvenile Song Sparrow (Melospiza melodia). This young bird can relax a bit longer than the distance migrators. Song Sparrows travel around just enough during the winter to keep themselves out of the worst of Michigan’s cold season.
A few other small birds appeared for me along the fence line. A little Eastern Wood-Pewee (Contopus virens) sings one of the most recognizable calls of a summer day – the rising “Pee – weeeee?” that sounds like an oft-repeated question. Birdsong beginners, like me, appreciate a song that identifies this little flycatcher who can be difficult to spot otherwise. Bob Bonin spotted a little Chipping Sparrow (Spizella passerina) who’ll be heading off to Florida before long. And he also saw a young Field Sparrow (Spizella pusilla) with its telltale pink/orange beak and feet.
Breeding Season Over, Adult Summer Visitors Relax Before Migration
My friend Bob brings patience as well as skill to his photography. He caught sight of two birds at the park that people rarely see and waited until he got the shot he wanted. One was a “leucistic” Savannah Sparrow (Passerculus sandwichensis) which means that it had partial pigmentation loss. Unlike the complete loss of pigmentation of albinos which also causes white, pink or red eyes, leucistic animals have partial pigmentation loss and their eyes are dark. Bob also waited over two hours for a closeup of another unusual bird, a Sedge Wren (Cistothorus stellaris) as it foraged for spiders and insects down in the dense grass, sedges and small shrubs within the fence. This is ideal habitat for Sedge Wrens, but since they are unpredictable nomads, we can’t count on seeing them every year.
Stony Creek Ravine hosts some more common summer residents as well – and we’re always glad to see them as well.
The plaintive cry of a Red-tailed Hawk (Buteo jamaicensis) fell from the trees around a marshy area filled with sedges (genus Carex), ancient, grass-like plants that thrive in moist ground. When it suddenly appeared overhead, I caught it twice with my camera, once like a magnificent arrow streaking across the sky, and once in mid-scream from a prey’s eye view. Glad I’m too big to be carried away for dinner!
Down Below, Butterflies, Bees and Late-Season Grasshoppers Harvested the Last of Summer’s Bounty
One of late summer’s most glamorous residents appeared in August, the glorious Giant Swallowtail (Papilio cresphontes), North America’s biggest butterfly. If you’d like to attract some to your garden, two of its favorite native plants are Rose/Swamp Milkweed (Asclepias incarnata) and all of the goldenrods, both of which bloom in late summer and early fall If you can also tolerate thistles, they seem to favor them quite a lot more than we do!
Giant Swallowtails are often seen on thistles. Maybe that’s why, by summer’s end, their wings are often a bit ragged. But this one was in its full glory! 
A head-on shot of a Giant Swallowtail sipping nectar. 
This shot, taken in 2017, shows the upper (dorsal) wings of a male Giant Swallowtail with its crossed lines of gold spots and golden-tipped “tails.”
At first glance, it’s easy to confuse the black and gold-spotted dorsal ( upper) sides of the Giant Swallowtail and the Eastern Black Swallowtail (Papilio polyxenes,) especially if they’re flying. But compare the ventral (lower) side of the wings. The underside of the Giant Swallowtail’s wings are yellow and the Eastern Black’s (below) are black. I was lucky to see both feeding at thistles during my visits to Stony Creek Ravine.
Smaller butterflies and moths float and flutter in the grass as well, of course – and one well-fed caterpillar just chews its way along.
My husband spotted this chubby Monarch caterpillar in early August.The white spots on its prolegs indicate it was probably a 5th instar and about ready to pupate. 
Chickweed Geometers (Haematopis grataria), lots of them, whisked from flower to flower at almost every step I took in the eastern fields. 
A lovely thumb-sized Eastern Tailed Blue (Everes comyntas) paused to sip nectar from a bloom near the woodlot. 
This summer resident, probably a Pearl Crescent (Phyciodes tharos) is only distinguishable from the less common (in our area) Northern Crescent (Phyciodes selenis) by a tiny white half moon on the underside of its hindwing. 
A female Clouded Sulphur (Colias phiodice) with its pink-edged wings catches anyone’s eye if it just stops frantically patrolling for a second or two! 
A Least Skipper (Ancyloxpha numitor) found nectar among the fringed petals of a non-native Chickory blossom (Cichorium intybus.)
As regular readers know, I’m intrigued by insects of many kinds and want to convince all comers to just enjoy them. So here are some of my other favorites during late summer at Stony Creek Ravine.
A very small, native Leafcutter Bee (Megachile species, family Megachilidae), so named for cutting neat circles out of leaves, rolling them, filling them with pollen and then laying an egg inside before sealing them up. The larva eats the pollen before exiting. Good provisioning! 
This photo is just a bit blurry because the Leafcutter Bee was vibrating to loosen up pollen that it collects in stiff hairs on the underside of its abdomen. It’s clear this was one dedicated bee! 
This dragonfly is some species of male Meadowhawk (genus Sympetrum) but the males of several different species in this genus are red, so I can’t be more specific. I love their intricate wing patterns! 
I believe this is my old end-of-summer friend, a Red-legged Grasshopper (Melanoplus femurrubrum). The females look very similar to the Migratory Grasshopper(Melanoplus sanguinipes) which doesn’t really migrate far; the adolescents mostly move short distances in swarms, especially out west. 
This Carolina Locust was photographed by one of Ben’s summer technicians, Emma Campbell. She and I both liked its auburn color since most Carolinas are beige/light brown. Dr. Parsons at Michigan State University’s Bug House tells me their color variation lets them blend in with different soils. 
Two tiny Hover Flies (family Syrphidae) were mysteriously attracted to the blossom on the right. I don’t really get the appeal, but…
Hardy Native Wildflowers Mix with Plentiful Non-natives until Restoration Advances.
Though the fields in the eastern section of the park have been cleared of many non-native shrubs, native wildflowers are not plentiful yet in the fields at Stony Creek Ravine Nature Park. The long stretch of native wetland Black-eyed Susans in the photo above is a glorious exception. Restoration of a healthy habitat with more diversity has begun with seed planting at this large park, but it will take several years to come to fruition. So I have to smile seeing sturdy native blooms holding their own amidst the non-native plants on the Outlook Hill, in the surrounding fields and near the wetlands. Here are some of the other stalwart native competitors declaring their presence at this amazing 268 acre park.
One native plant that’s rampant at the park this year may not please everyone – Common Ragweed (Ambrosia artemisiifolia.) So if you suffer from hay fever, now is not a good time for your visit! Please remember, though, ragweed pollen is dispersed by the wind; that’s why it ends up in noses. So please don’t blame your sneezing on innocent goldenrods that bloom at much the same time. Their pollen is heavy and falls right to the ground, far from sensitive noses!
Oh! And One Creepy Fungus that I Just Have to Share!
One of the benefits of being in a birding group is having more eyes and ears seeking out interesting details in the landscape, plus access to other people’s areas of expertise. For example, the energetic, hardworking summer natural areas stewardship technicains each year provide me, at least, with younger eyes and ears, youthful enthusiasm and a knowledge base more updated than mine!
In late July, while walking up the path to the ravine, Emma Campbell, one of this summer’s technicians, stopped to comment on a spiky bump in the trail that most of us stepped around, assuming that it was just a sharp piece of root. But Emma carefully broke off one small portion and finding it white inside, correctly identified as a fungus spookily called Dead Man’s Fingers (Xylaria polymorpha). Evidently it’s a common fungus that grows from rotting wood; as you can see below, this one emerged around the remains of a stump. What a Halloween-ish discovery! Thank you, Emma! Wish I could have creeped out some friends with this one when I was a kid!
The “Oohs” and the “Ughs” of Nature’s Impulse to Keep Fostering Life
Unless you are a hopeless romantic, every close observer of the natural world knows that nature is not all “sweetness and light.” The lives around us in nature can be both big and beautiful like the Great Blue Heron (Ardea herodias) or small and homely like the Fall Webworm (Hyphantria cunea). It can be full of tenderness, like birds tirelessly feeding their young or ruthless in its need to survive, like a hawk tearing the flesh of its prey. It can be inspiring like a flight of fall geese or macabre like the Dead Man’s Fingers fungus. But whatever qualities it has for us humans, nature itself doesn’t judge and never despairs. Against all odds, nature just proceeds eon after eon in service of sustaining life, whatever that takes. The “nature of nature,” as it were, is to adapt, survive and assure the existence of the next generation.
We humans, as just another species, would do well to take a lesson from the creatures and plants that surround us. We cannot afford to despair as our behavior changes the climate, threatening life on this special blue planet. Generations could stretch on into the future indefinitely if we would do as all other creatures have evolved to do – adapt, change, survive and above all, work hard to ensure that long after we’re gone, life continues on a healthier path than we’re on right now. If we do, our grandchildren and their descendants will honor our efforts and that honor will be well deserved. Let’s not disappoint them.
